Are there any best practices for efficiently counting records in a MySQL table using PHP?

When counting records in a MySQL table using PHP, it is important to use efficient methods to avoid unnecessary resource consumption. One common approach is to use the COUNT() function in a SQL query to directly retrieve the count of records from the database. This reduces the amount of data transferred between the database and the PHP script, resulting in faster execution. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to count records in a table
$sql = "SELECT COUNT(*) as count FROM table_name";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    echo "Total records: " . $row["count"];
} else {
    echo "0 records found";
}

$conn->close();
